Pragmatic Play's John Hunter series has several entries, but John Hunter and the Tomb of the Scarab Queen is still one players bring up often, thanks to a multiplier-stacking mechanic that can run for a long stretch.
Theme and layout
The theme is an Indiana Jones-style treasure hunt set in an ancient Egyptian tomb, on a 5x3 grid with 25 paylines. Symbols include the adventurer, an Egyptian queen, and a sacred scarab beetle, with a mysterious, exploratory atmosphere throughout.
The mechanic that made it stand out
During free spins, every scarab beetle symbol that lands adds to a running multiplier total. As long as at least one scarab lands on a given spin, the free spins round keeps extending and the multiplier keeps growing — giving the bonus round more potential length than a typical free spins feature with a fixed number of rounds. A bonus buy option is also available for players who want to jump straight into the multiplier-stacking round.
Who this suits
This suits players who enjoy a free spins round that keeps extending itself, where the outcome hinges on how many scarabs keep landing in a row. Volatility runs high, so it rewards players with plenty of patience.
Summary
John Hunter and the Tomb of the Scarab Queen shows that a self-extending multiplier mechanic can create excitement quite different from a fixed-round free spins feature. See more on the game page or explore other titles from Pragmatic Play with a similar stacking-multiplier mechanic.
